[英]IOS Push Notifications sound not coming
I am working on Ios push notifications where I am able to get Push notifications. 我正在处理Ios推送通知,可以在其中获取推送通知。 But problem is I am not able to get any sound when receiving a Push notification. 但是问题是我在收到Push通知时无法听到任何声音。 I have checked my Notification center also and there I have enable sound already. 我也检查了通知中心,并且已经启用了声音。 My code is given below, kindly guide me how to fix this issue. 下面给出了我的代码,请指导我如何解决此问题。
@UIApplicationMain class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
UNUserNotificationCenter.current().delegate = self
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) {
(granted, error) in
print("Permission granted: \(granted)")
guard granted else { return }
self.getNotificationSettings()
}
return true
}
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void)
{
completionHandler([.alert, .badge, .sound])
}
func getNotificationSettings() {
UNUserNotificationCenter.current().getNotificationSettings { (settings) in
print("Notification settings: \(settings)")
guard settings.authorizationStatus == .authorized else {
return
}
DispatchQueue.main.async(execute: {
UIApplication.shared.registerForRemoteNotifications()
})
}
}
func application(_ application: UIApplication,
didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
createInstallationOnParse(deviceTokenData: deviceToken)
}
func applicationWillResignActive(_ application: UIApplication) {
}
func applicationDidEnterBackground(_ application: UIApplication) {
}
func applicationWillEnterForeground(_ application: UIApplication) {
}
func applicationDidBecomeActive(_ application: UIApplication) {
}
func applicationWillTerminate(_ application: UIApplication) {
}
func application(_ application: UIApplication,
didFailToRegisterForRemoteNotificationsWithError error: Error) {
print("Failed to register: \(error)")
}
}
Add 加
class AppDelegate: UIResponder, UIApplicationDelegate , UNUserNotificationCenterDelegate {
as when you do 就像你做的那样
UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate
the delegate isn't retained so , willPresent
method isn't called , so do 不会保留委托,因此不会调用willPresent
方法,因此
UNUserNotificationCenter.current().delegate = self
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
if #available(iOS 10.0, *) {
let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
UNUserNotificationCenter.current().requestAuthorization(
options: authOptions,
completionHandler: {_, _ in })
// For iOS 10 display notification (sent via APNS)
UNUserNotificationCenter.current().delegate = self
} else {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
return true
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let token = deviceToken.map { String(format: "%02.2hhx", $0) }.joined()
print("tokenMyDevice : \(token)")
}
func application(_ application: UIApplication,
didReceiveRemoteNotification userInfo: [AnyHashable : Any],
fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
print("get push : " , userInfo , UIApplication.shared.applicationState )
}
Read the fail error here 在此处阅读失败错误
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
print("failed to register for remote notifications with with error: \(error)")
}
@available(iOS 10, *)
extension AppDelegate : UNUserNotificationCenterDelegate {
// Receive displayed notifications for iOS 10 devices.
func userNotificationCenter(_ center: UNUserNotificationCenter,
willPresent notification: UNNotification,
withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
completionHandler([.sound,.alert])
}
}
